EYELETING ivrecnnn.`

\ most universally beenarrangred with a punehcarrying; head movable froma stock punch-` inn' position to an eyelet inserting,r and setting p(iti0n, for cooperating with relatively stationarv eveletdioldingf vandclinching mech,

sin. The punch-carrying head is pro-` ced with a reciprocatingcombinedtubular ich and anvil7 thel punch 1n one position ot tue head operatingupon a stationaryltable l or cutter block, andl after a. ptnchingg,Poperano, by `the movement oi' the head, is posi ti oncd `over theeyelet-hcldmp; and. clinching 1 invchanisni..y The holder comprises arecipicating spindle, whichV concentrically rethe eyelet,` and theclincher, as a recnirocating sleeve telescoping` over the spindie isadapted to cooperate Witlrthe anvil ion ot' the punch..` For aneiiiicient opera- ;fi ret the machine and perfect eyelet-setnog, it isessential that absolute alignment registration of the opposinglcocperatingg` frts he m intained, forthe slightest disalignment willresult in either injury to the punching andsettingr tools or to theeyelets. The eyelets used in high, speed machines are usually ot' averysoft ductile material,` and are more susceptible to injmy-through dis- Halignment and non-registrationof the tools than the tools Which are'ofhardened steel. in higgh `speed machinesnhaving the Working parts` asmentioned, vibration Aand hearing play of theparts rendersiitmechanically imsible to effect thenecessary valignment and :tration of4the opposing neyelet-settinpr tools, and results in, thefreouentbreakingot the tools and constantrimperfect eyelet-- ting, asclenching;r the eyelet more on one side than on the. other, and notannularly uniform,

and when the eyeletsare enamel inishechas geneally used in shoe uppers,thev enamel coating is marred and chipped. j

`,ln the present invention, the opposing cooperating tools are-supportedand reciprocated in avunitary frame structure in constant registration,and the tools move unitarily with their supportingr fra-Inc or carrierwith any lateral or `transverse motion of the same.

, 4fed for a` The carrier is translated from a punching y position to apredetermined eyelet spacing distance vfor a Work` feeding operation.andto move the toolrbelvond a stationary cutting table or bloeit. 1 1 Anobject et the invention is to eliminate the `shove mentioned objectionsof imperfect cyclist-setting. and relatively "sloiv machine operation,by providing annitary tool carry-A` infr-traine. f `This results in anincrease in the lifej of the punchingr and eyelot-settingr tools and aperfect eveletsettinng and also enables the machine to be operated at aconsiderably` higher rate ot speed than heretofore.

ther objects are to simplify andimprove the adjustment of the punchingrand setting! tools` to coactino' eyelet-settiuga positions, and tosimplify and improve the adjustment of thecomhined punch and anvil forits proper Contact with the punch block. 1 I An additional object is" topermit the convenient and rapid removal of either or hoth,`

combined-punch and anvih and eyelet holder` and clinchcr for purposes ofsubstituting other typesof the same, or for any` other purposesWhatever. Another object isy toV provide :fi/manually operated feedadjustment, enabling a rapid feed change, to give alternate short orlong eyelet spacing', at the willV of the operator.

Another object ot the invention is the'pro- Vision `oit means wherebythe eyelet holderfv is caused to move at different speeds duringdifferent portions of its cycle of movement. From its normal orstart-ing,- position the eyelet holder is caused to move slowly to itsreye@` let engaging position in order to secure prop-V er engagement Withthe evelet heldvyieldingly at the end of the racevvay; then after theeyelet has been delivered the eyeletholder movesV at an increased rateof speed to the point atwhich the setting of the eyelet is to takeplaceV and after that hasbeen accon'iplished the eyelet holder thenreturns `to its initial or start-- ing position at its greatest rate otspeed.

Another object is to provide tor the conven- I ient attachment andremoval of the eyelet reservoir andraceway for purposes of substitution,as the requirements rtor diiferent styles of eyelets'may demand. Fig. `lis 4a general perspective vievvof my. improved rapideyeleter. f

In the drawings, the easing, housing or support tor the mechanism isgenerally indicated at 1. The main drive shaft is shown at Q. (sce Fig.3)., is supported in elongated hearings l and 1, and extends to theright heyond the casing l, to support the drive and clutch puh ley 5,and part et the clutch mechanism. all hereinafter described in detail.

rl`he reciprocating punching and eyeicting tools are arranged incooperating opposingl positions. as uppe and lower, and are respectively mounted in relatively opposite bearings of a laterallytranslatable head or trame otI yoke design, to provide a work-receivingthroat hetwcen the opposing nppcr and lower tools. The head nnitarilj.'support s the tools :tor constantly maintaining their cw operatingalignment and registration irre spective ot any lateral translation o t'the head.

The tools are recipro' fated by the l'ollon'- ing` mechanism, (see Figs.9. and Il.)

Mounted upon the main drive .shalt at its inner extremity, is a disk orrotor (l. having upon its inner surface a semi-circular cc centricgroove 7, (see Figs. Q and 15)) the een ter 8 ot which is eccentric tothe axial center 9 of the shaft 2, the center line til oi' the groove 7passing through the axial center il of the said sha'ttv 2. A segn'ientalor :ecmiwii cular eccentric block 1l slidingly 1n-@initrd within theeccentric groove T ol' the olor and the said block has an opening l2.r(scc Fig. 18), near one ot its extremitie through which a pin 13extends. This pin is eccentrically carried by a disk 14, mounted upon ashaft 15, the axial center ol which is in vertical alignment with theaxial center ot' th'.I shaft 2, but horizontally helon' and ecceiztr'ntothat shatt.

The shaft 15 is supported in a huh hearing cap 1G, secured to the leftside of the cas-.ing 1 as a closure for the port; opening through thecasing, through which the crank disks are inserted to assembling theparts in conner- `ing with therock lever 19, fulcrurned upon the crossshaft or ro`d20, supported in the bearingsl)El of the casing 1.

The forward end 2,1 of the lever 19, is offset laterally, (see Fig. 22),and its end forked as at 22 for the reception of, and pivotal connectionwith a turn buoi-:le block `23, the said block and fork arins beingtraversed by "a pivot 24. The block 23 is provided with an upstandingright threadedstcin 25, designed to coact with the corresponding'threadsof a turn buckle adjusting nut V26, the upperportion of the nut havingleft threads for coaction with a correspondingly left threaded stein 2T,projecting dowm'ardly` freni aiturn buckle block 28, pivoted at 29 `to aslide nieine ber 30. The slide member o0 isi-sustained in guides 31,formed at the frontand as a part of the casing,land is capable(ii-"vertical re` ciprocation therein. Gib plates 32, pivoted at 33 tothe guides 31, holdthe plunger 30 in position withinthe guide-way- Theplates arcprovided near their upper ends anden their inner opposingedges with slots 84, these slots being concentric with the pivots andtraversed by winged clamping screws 35, for holding the plates in theirproper positions. Fastened upon the upper outer edge of the plunger 30is an anchoring plate 37, inthe forni of an angle-iron, the horizontaledge of which engages a notch `38, of the lower toolcarrying plunger 39,the bottom of which rests upon the slide member 30; The knurled nut 26is provided on its lower circumference with teeth Ll0, Vengaged bya pawlspring Zil.,

`to hold the nut inits adjusted position.

When it -is-desired to Araise or lower the plunger toadjust the-toolplunger thereupon, the lnurled nut 26 isrotated, rnd by its turnbuclrleaction*inicroinetrically Vadjusts the slide member and its connectingparts, either upward ordownward, as may be required.

LThen it becomes necessary to remove the tool carrying plunger, thewinged clamping screws are loosened' and the plates 32 swung outwardlyand downwardly about their pivots 33, to a horizontal position, to

bring their lower edges in vertical alignment and flush with the innervertical' faces of the guides 31, releasingthe slide ineinber 30, forpermitting the lower end thereof to be pressed slightly outwardly by theaction of the'spring 41 and disengaged from the guides 31, and adaptingthenieinber to be swung downwardly about the pivots 2d and29, to aposition shown in Fig. 7, disengaging the anchoring plate 37 from thenotch 38 of the she tool plunger 39. The tool plunger 39 is slidablyheld in the bore of a laterally translatable tool supporting head 51,traversed by and rigidly attached to a lower guidebar 52, capable ofreciprocation in bearings 53 and 54; of the casing 1, and traversed byand slid- 'l able upon an upper stud shaft 55, rigidly heldV at 56 inthe casing l, to support and guide the v upper portion of `the toolsupporting-head 51.

The head 51 is ofyolre design, providing upper and lower oppositealigned tooll supporting and guiding arms, and for unitarily carryingthe tools in the lateral translation of the head for feeding the workover a vpunchblocl; or table, for a definite eyelet spacing in the work.A' bore '57 in the upper arn'i of the.` franieor head 51 slidablyreceives the tool plunger o7, the bores 50 and 57a being always'invertical alignment to assure absolute alignnientl and registration forVthe op .posing cooperating tools, essential to an eiii cient operationof the parts athigh speeds, and to a `perfect setting and clinching ofthe eyelets, without injury to the tool or eyelets.

The upper tool-holding plunger 57 is pro` vided with a notch()`v at itsrear side, into which the edge of a guide and anchoring plate 61projects, the plate being rigidly attached to forward arin k63 of theupper rock lever 62, having a bore 63a, traversed by an eccentric bushhearing- 6ft, which in turn is traversed by a removable shaft 65, thesaid vshaft being slidingly held in bearings 66 and 67 at the upperforward side of the casing 1above and rearwardly ofthe stub shaft 55.The eccentric bush bearing 64 on its right end vis provided with acranl?` arin 65:", having atlits Outer extremityla spring pressed detentpin 65", designed to engage with anyof a` series ofopenings 65, providedin a quadrant plate 68, integral with the upper toolactuating lever 62.When the` detent 'pin A65b is withdrawn from one of the openings 65,\andthe arni 65 rotated forwardly, the action of the eccentric bush bearing64 lowers or adjusts the lever 62, and consequently, its connected toolholding plunger for vertically adjusting the upper set of tools.

lWhen it becomesv necessary to reinove the upper tool-holding plungerv57 for' substituting` a ditl'e it kind or size of tool,vthe alr6 iswithdrawn `from the bearing 67, andfronfi Vthe bore of the erm nticbuslrbearing 641-, allowin@r the lever t to be swung upwardly about` tiepivot '17C' of the toggle link ngages the anchoring plate 61 in thenotch of hetool-holdingplunger 5.7 and allows its withdrawal. from thehead. The shaft inay then be r sorted within the bearing' 67. to `f n aVrest for the Vlever 62 in its raised po The operation of replacing thecolnbin c.. upper tool-holding plunger isthouglit to be obvious from theabove description of the reverseoperation.

The mechanism for actuatinpr or reciprocating the upper tool-holdingplunger comprises; the following parts.

The arm (533 ot the lever (l2 is pivotall)v attached by a pin 70, to theupper tork T1. ot a, double forked toggle link 7:2, the lower 'fork 73of which, etraddles the forked arms T5 oi a forked toggle TG rotativel)4mounted upon a shalt 77. which Shaft is in turn mounted ro tativel)v inbearings TS and 7S) ot the casinar 1. extendsv outside ol.' said casino,is provided at its lel't outer end with an adjustable lever arm SO andat its rigrbt end with an c velet racewa)7 trippineY roller arm 81.

The outer-*end of thefoijl-:ed link 121 is pivoted to theup'per side of theguide bracket 137,as .at 121, the said link acting to prevent lateral movement oit theswinging link bar 125 during the, forward and rearward movements of thepitmun 113 and-of the link 116 `connected therewith. As before stated,the cross slide bar 135 is laterally slidable in the guide brackets 136and r137, to change the fulcrum point of the swinging link bar 12.5. Asshown in the drawings, the carriage 135 and its fulcrum head 127 arepositioned to give the .ordinary minimum length of work feeding throw tothe head 51.

`In order to=increase thelengthof .feed for sett-ing the` eyelets. at amaximum distance apart, the carriage 135 is moved to the right to changethe position-of the fulcrum block 127 and manually operated means isprov vided to move tbecarriage and to limit this movement, adescriptionofwhich follows` Pivotally attached as at 166 to a lug on theguide bracket- 136 (see Fig. 4) j is an arc shaped lever 161, the lowerend of which is pivoted at 162 to a link ,163 and the opposite endotthis link is pivoted` at 1611 to a lug 165, cast upon the under faceof the carriage 135. To the upper outer end of the arc shaped lever 161(see Fig. 4) is pivoted at 166, a rod 167, suitably connected with atoot treadle (not shown). The operator depresses tbe rod 167 and with itthe lever 161, and, as a result, torcesthe carriage 135 tothe right,(Fig. S), lett, (Fig. 4), to a distance`determined by the adjustment ofa set screw 170, mounted at the end of the ,carriage 135, and enactingwith the guide bracketv 136, the can ringe being returned and maintainedin its initial position by the action oi a spring 171, the terminale of:which are fastened at 17 Q,

17 3 respectively, tothe casing 1 and carriage` Anadjustablc stop'174 isprovided at the right end of the carriage 135 (Fig. 8), to limit themovement of the carriage against the action ofthe spring 171, the saidstop coacting with the outer surface of the guide bracket 137. j

The operation of the feed mechanism will be obvious from van inspectionof Fig. 8,

`wherein dot-andfdash lines show the posi-V tions oi the various feedelements when'the tool carrying head57 posltloned for an eyelet-settingoperation.. In virtue of action et the tced mechanism above describedthe spacing or' eyelets caribe, quickly and accurate'y varied, andalternate long or short spacingcan be accomplished by simple adjustmentot' the stop screw`170, in conjunction with tbe depression of the lever161, to change `the Lulcrrun` point of the slide bar 125. YVhcn itdesired to alternate from shertto long spacing, the carriage is shiftedby actuation of the -lever 161 and when a short spacing is again desiredthe lever 161 and carriage is released, whereupon the s rinof 171automa-ticall f returns the carria el head 127 tothe initial carryinghead can therefore be varied at the i will of the operator, while themachine is in motion, within predetermined limits permit- I ted by amaximum movement of the carriage 135, for which the carriage was set bythe stops 170, 1741. To exemplify this feature, let it be presumed thatthe maximum movement for the tool headteeding stroke is two inches, andfor such maximum stroke the set screw 170 outward, to` permit the stopplate 0n theV lett end of the carriage, (Fig. 8), t0 strike against themachine frame or carriage bearing bolted upon the trame.` The levermechanism in connecting the tool head with the pitman. would then throwthe head in each revolution of the cam 110 or full reciprocation of thepitman 113 a full maximum stroke ot two inches, as long as the operatorkept the lever 161 depressed or the carriage positioned toits extremeright limit. TheV carriage could be. permanently set in such position byset screw 174,113 occasion reeV quired, or the spring 171 removed, whichwould permit the carriage to remain in any adjusted position. The partsare designed for a constant minimum distance of head feed reciprocation,for moving the tools to an appropriate position over the table or cutterblock, which, in this instance, is ,station` ary for a work perforatingoperation, and to :inappropriate position clearing the table, a cutterblock for` un eyelet inserting and clinching operation.. If the cutterblock was movable, the minimum head movement would not be required. Theminimum punch lblock clearing movement may be said to measure onequarter of an inch.' The operator therer fore can at random change thereciprocating stroke of the head correspondingto thedegrec he moves thecarriage 135, so that the head can have areciprocating stroke of itsminimum onequarter inch toV any degree up to its maximum two inches. Themaximum for manual treadle control is fixed by the` degreeof stopadjustment of the stop screw carriage appropriately for a one inchstroke of the head, vwhileits minimum stroke remainsv constant.

axis of the swinging link 125, thus increasing or decreasing its levermotion transmission The adjustment ot the' stop screw 1741 is primarilyfor bringing the to the parts connected to its tree end. The tulcrum torthe link 125 when moved toward the end of the lever connecting yoke 120,ot the connecting rod, increases the are o t movement at the oppositeend o? the link, increasing the head stroke and conversely when thelfulcrum is adjusted in an opposite direction. The cam throw and pitn'ianstroke is constant and the head stroke variable.

rl`his is ot' considerable advantage when applying the eyelets upon shoeuppers, as it enables the operator to change the eyelet spacing whilethe machine is operating at high or Jfull speed, it being desirable tochange the eyelet spacing at curved portions 'tr m the spacing towardthe upper end of the upper or lower end.

The work is supported upon a table comprising an attaching base 181(Figs. 1 and 2) provided with a lng 182 upon its under tace, the sameresting within a corresponding groove 183, formed in a projection 1811,aty the front right side ot the easing 1 and held therein by a headedscrew 185. The base 181 is formed with a projection 186 extending up-'ardly and horizontally z lross the easing 1, between the upper andlower tools ot the head, and is supported at its outer end upon ashoulder 18T at the opposite side ot' the casing 1. Extending forwardlyfrom and torming a part ot' the projection 184 is a horizontal work restor table 188, having a slot 189 formed lengthwise there across, thisslot being so positioned in respect to the upper and lower tools as topermit them to centrally trziivfnse the slot', during the work feedingand eyeletsetting operation. The slot 189 is of sutlicient length toallow the tools to traverse the saine at the maximum stroke of the toolcarrying head 51. The punch block 190 is counter-.sunk within the workrest, 188 and positioned beneath the punch and 4set. .37, when the toolcarrying head 51 is in its normal position, the upper surface of' thesaid`block 190 being slightly below the upper surface of the work rest,in order that, alter the stock has heen punched and the punch has beenreleased, and after tool head has moved to its eyelet-setting position,the shank 191 of the upper tool will in its downward movement to meetthe set, be forced into the opening in the stock to positively and morerigidly hold the same against the upper surface of the work rest 188. Aslotted gage 198 is adjustably tastened by a screw 1911 to the uppersurtace ot the work rest 188 rearwardly of the tool 57, and provides anotch 105 at its forward end, into which the edge of the stock isinserted to guide the same. A presser foot 200 ot U- shaped formationsurrounds the slot 180, and contacts the work rest 188, or the uppersurface of the stock when the machine is in operation. The. U-shapedpresser toot 200 is open at its right, and at its back is provided witha rearwardly extending lever arm (Fig. 2)

rlhe detailed operation oi the stoel; pnnching and eyelet-settingoperations can best be understood from an inspection oli Figs. 2, iii,33, 3st and 35, the tour latter views being in diagrammatic form.

The initial position ot the n'ieclianism for performing theabovementioned operi-.tions is shown in Fig. 2, wherein the uppertoolholder 57 is at its upmost limit and the lover tool holder 39 at itslowermost position. Upon rotating the main drive sha'i't Z in thedirection ot the arrow through an arc approimately two operations aresimultaneously performed, (see Figs. 2, 82 and 33). The cani 105,coaeting with the pitnian 95, throws the pitman forwardly to torce thetoggles 72 and 7G, also forwardly. bringing the axial center of the pin85 in vertical alignment with the axial centersl ot the pivots To andTT, of respectively the upper rock lever (i2 and toggle 7G, to actuatethe rock lever (32, i'orcing the upper tool holder and its toolsdownwardly to punch the stock, a continued movement of the pitmanforcing the pin tlf forwardly, out ot vertical alignment with the pivotsTO and 7T, raising the tool holder .sli "hi ly to bring the punch oli'of the table cntti block preparatory to the eed operation.

rlhe punch, in its descent punching through the material on the punchblock, has its descent regulated for coming to a stop when the punchengages the punch block, thus causing` complete punching without injuryto the punch or punch block.

Simultaneously with the above described operation, the disk andsegmental eccentric block l1 sliding in its groove T, and connected bythe eccentric pin lf3, of the disk lei., to the set lever link 19,operates to raise the outer forward end 21, ot the lever 1f), toroperating the lower tools, to move the lower plunpi till and tool holder3f) resting thereon upuardlj,r i'or threading the eyelet teediiig andguiding spindle through an evelct at the end ot the racc-way, andpositioning the eyelet l'or driving the same through the perforation inthe work, and subsequent clinching. The eyelet :Feeding and centeringspindle is yieldingly sust ained in the holder.

The eccentric action oi the disk (l and its related parts causes arelativelyY slow movement ol. the pin 13 during the iin-:t quarterrevolution of the said dish, wi th a correspondiugly slow upwardmovement ot the lower tool holder 39 to eyelet engaging position. thusinsuring the proper tool engagement with said eyelet. After engagementwith the eyelet, the upward speed of the tool holder gradually increasesand immediately after the. setting operation, the downward .speed of theholder is e-itrenielyv rapid, thus a voidinpr the possibilit)v ofcollision with the work roest or with the eyelot raceway. since the toolhead 5l moves direetlvv after the said settingT operation. 1

Referring to Figs. l. il. 3G. 53T and 3S. the drive and clutch pulley 5is .shown loosely and rotativelv mounted upon a (,-ylindrical hub memberlill). rigidly attached to the shalt Q hv a pin `lill. rlhe bore 1.102.o'fi the clutch and drive puller 5, has l'ormed upon its inner sur'laceand at the outer edges of the. same,` shalhiw segmental depre nis -`103,their inner surfaces being depressed in respect. to the bore 409. andthe endsl of the depressions form stop shoulders t0-l for coaction withpulleyY brake means mounted within the hub member 100. The hub member isprovided rneeeee with a transverse horizontal bore 405. adjacent itsperiphery, into which is rotatively placed a shaft 406, having eccentriccylindrical projections 407 at each of its` ends, upon which arerotatively mounted brake collars 408, desi'ned to coact with the shallowdepressions 403 and shoulders .404, of the bore 402, of the pulley 5, topositively clutch the saine when forced outwardly thereagainst. Fastenedto the hub men'iber 400 at its inner face is a dished circular' brakehousing 10, open at one side and attached at its closed side to the hubmember. 400, as at 411, and is provided with a brake flange 4112L ferengagen'ient by brake shoes, hereinafter described. j y

A lever 412 is adjustably fastened to the inner eccentric projection407, and at its lower end is provided with .an outwardly projectingstoproller 413. A spring 414 is connected to the lower end of the lever412 and to `the housing 410 and acts through the medium of the lever412, shaft 406 and eccentrics407 to force the brake Collars 408 intoengagement with the depressions 403, and subsequently with the shoulders404 to positively Connect the pulley with the hub 400.

shown in Fig. 36, the brake collars are disengaged from. the inner.surface of the pulley bore, the springV 414 is under tension, and thisposition of the clutch parts corresnonds to the initial position of themechanism of the eyelet machine, as shown in Fig. 2. ln this position,the roller 413 is engaged with a stop arm 416, depending from alaterally slidable collar`417 mounted upon the shaft 2. provided with aperipheral groove 418, and with ahubprojection 419, having upon itsright a peripheral involute cani 420,

`for engagement with the roller 413, to force the said roller and itsconnected lever 412 to brake collar disengaging positiontorelease thepulley 5.

`A slight rotationof'the collar 417 and its depending stop armk 416, ispermitted by a yielding horizontal stop shaft 422, mounted slidingly inlugs 423, projecting from the casing 1, against the end 422a of whichthe rear face of the depending stop arm 416` rests. i The rear `end 422`of the shaft 422 has ,connected to it, as at 426, a lug 428, to which isattached one end of a springl 425, the opposite end of the same beingfastened as at `427 to the top ofthe bracket 137. The function of thisspring 425 is to yieldinglyv counteract `the shocks `communicated to thedepending stopA arm y416,. by the roller 413. as it engages Vthe saidarm. The rotation of the shaft 422 in its bearings is preventedgby itsattachment to the arm 4282 the outer end of which slid- Y ingly engagesa pin 429 held by the rearwardmost lug 423. v j

Mounted upon. the extended ends of the shafts -98 are brake actuatinglevers 430 and 431, whereof a description-of cachend of theiroperationfollows. The leverv 430is adjustably clamped upon a bushing43l,.this bushing being mounted loosely upon the shaft 98 and having abrake shoe arm 432 at its outer end. `The lever 4301projects rearwardly,downwardly, and in alignment with and beneath the rolle-r 413, and isdesigned to be engaged with and depressed by the said roller in itsrotative movement and before its engagement with theV stop. arm` 416,`to force the brake shoe 432a attached to 'the brake shoe arm 432 intolengagement with the brake flange 411e. Mounted loosely between thelever 430 and brake shoe arm 432, isa stopV lever 435, the lower end 436of which engages the roller 413, to prevent its disengagement from thestop arm 4116. The roller depresses this stop lever 435 against theactionof a spring 437, fastened at 437a-437 respectively to the brakelever 430 and tothe saidV stop lever. f

. The brake actua-ting lever 431V is mounted loosely near the-end of andupon the rearwardmost shaft 98 and extends vertically downward. itsfront-face 440 engaging the V'end 422b of the shaft 422 by which. itisforced outwardly `to bring the brake band 445j`into engagement with Vthebrake flange 411@ when the rolle-r 41.3,strikes the projection 4.16 topositively prevent further rotation of the shaft 2. A pin` 441 projectslaterf ally from the lever 431A and contacts a. compression spring 442,adjust-ably mounted as at 443 in ai lower depending arm 444 of the brakeshoe lever445, the said brake shoe lever being loosely mounted foroscillation` onthe shaft 98, adjacent the outer face oft-helever 431. Ahorizontal arm 446 projects rearwardly from the brake shoe lever 445 andat its outer end is provided with an upwardly extending adjustable setscrew 447. the head 448 of which is designed for engagement with anddepression by-an arm 450, adjustl ably clamped at its hub end to the endof a rotatable shaft 451, parallel with and above the shaft 422, andheld` in a. bearing 453, of the casing 1. At theforward end ofthe shaft451 is adjustably clamped .depending tripping arm 454, provided at itslower end with a. pin- 455, engaging the groove 418'of the collar417.Upon the depression of the arm f 450. by. the operator, the collar 417is forced to the. left to disengage the stopY arm 416 from itsengagement with the roller 413, to allow the brake collars 408 to engagethe hubV de'- pressionof the constantly rotating pulley 5, to set theeyelet machine in operation.A The arm 4501is depressed by the operatorthrough nie-ans of a tre-edle', (not shown), connected to chain 460, theupper end of which has a hook. connection 461, with lthe outer end ofthe lever 450. l

The brake actuating leversv430 and 431 are, in rapid succession causedto bring theirrespective brake shoes into contact with the brake fla-nge411, the lever 430 being irst actuated by the roller 413 as itapproaches tor engagement with the arm 416, and the lever 431 beingthereafter immediately actuated as a result of the collision of theroller 413 with the arm 416, the rearward motion ot the said arm beingcommunicated to the shaft 422 and from it to the lever 431.

counter stop 457 is attached within the groove 418 in substantiallydiametrical relation to the Stop ariii 416. and abuts the end of theshaft 451, its Yfunction beiner to prevent counter-rotation ot collar41T, after the stop arm 416 has been engaged by the roller 413, and whenthe shaft 422 is retracted by the spring 425.

An arm 465, projecting vertically trom the hub ot the arm 450. isprovided with a. spring 466, attached at 46T to its upper end, and at468 to the easing 1, the function of the said spring and arm being toautomatically return the projection 416 to a position for engagenicntwith the roller 413 when desired.

dien the roller 413 is released from contact with the stop arm and movesinwardly under the action of the spring 414, its inner fiat facecontacts the outer tace ot the arm 416, and slides tliereagainst, itsfurther inner movement being prevented by the ed ge ot a circular washer41.9", equal in diameter to the diameter oi the hub projection 410;these. contacts are maintained until the Forward peripheral edge ot theroller passes the rear vertical edge of the arm 416.` at which time thecollar 417 and attached involute cani 420 are thrown to the right by theaction ot the spring 466, to briner the cani into a position forengagement by the roller 413, to force the same outwardly, to release.the brake collars 408. This release takes place before the shaft 2, andcorrelated mechanism reaches its initial position, the momentum et themachine completing the initial setting of the said mechanism.

In Figs. 39 to 42 inclusive, I have illustrated a torin of' punch blocktor use in stock, upon which is sewed a military stay7 strip. Muchdifficulty is experienced in setting eyelets in these strips, inasmuchas the right or fair si de of the upper, faces downwardly, andconsequently provides no means whereby the. worker can locate the pointof insertion ot the eyelet with sufficient accuracy. I overcome theabove difficulty by providing a circular punch block 500, provided uponits upper face with a groove 501, the width of which is sutlieieiit toallow an easy sliding movement of the stay tlierewitliin. The punchblock is provided with a depending pivotstud 502, which traverses thework table, to allow a rotative movement ot the attached block. Abroad-headed screw 5053, is threaded into the lower end ot the stud thehead ot the saine engaging` the under side of the work table, to preventwithdrawal or displacement o the block, but to allow its t'ree rotativemovement coiii'ioriiiably to the requirements, as determined by thecurvature ot' the sta-y strip :305, scwed to the up per 506.

As shown in Figs. 41 and 42. the stay7 is inserted and guided in thegroove .301, of the pivoted punch block.

The above described construction provides a means for accurately andautomatically guiding the stay to successive eyelet-setting positions.
